药物涂层球囊在冠状动脉分叉病变中的应用研究进展

冠心病是指冠状动脉发生粥样硬化引起管腔狭窄或闭塞，导致心肌缺血缺氧或坏死而引起的心脏病，有效的血运重建是冠心病患者治疗的关键。近年来，冠心病介入治疗技术发展迅速，取得了巨大进步，但分叉病变作为一种复杂的冠脉病变，其处理仍面临巨大的挑战。药物涂层球囊（DCB）是冠心病介入治疗领域的新技术，研究证明，DCB在治疗分叉病变方面具有较好的有效性和安全性。现就DCB在分叉病变中的最新研究进展进行梳理和综述

Research progress in the application of drug-coated balloons in coronary artery bifurcation lesions

Coronary heart disease (CHD) is a kind of heart disease caused by stenosis or occlusion of coronary artery caused by atherosclerosis, which leads to myocardial ischemia, hypoxia or necrosis . Effective revascularization is the key to the treatment of patients with coronary heart disease. PCI, as one of the revascularization methods, has been widely used in clinical practice. However, the treatment of bifurcation lesions in coronary artery lesions still faces great challenges. Drug-coated balloons are a new technology in the field of interventional therapy. A large number of studies have shown that drug-coated balloons can better deal with coronary bifurcation lesions. This article summarizes the introduction of bifurcation lesions and drug-coated balloons, and the application progress of drug-coated balloons in bifurcation lesions
